VDO MC 1.0+ computer
Anyone have the VDO MC1.0+ computer? Just picked one up at PB for $64. Has a barometric altimeter. How's the accuracy?

Depends on the degree of change in atmospheric pressure over time after calibrating for home altitude. It can be very accurate, or off a bit. It is great for recording grade percentage and climbing totals.

That is what I was thinking. Might not give precise altitude measurements, but it should give accurate total climb numbers and incline stats.

I use a Garmin 500 now. I did use the VDO for a long time. It's accurate enough with elevation, as I noted that repeat climbs always yielded similar results. +1 to Wekin's comments, above.

Last night I set it up. My house is at 446 feet. Plugged that in the computer as the base altitude. This morning the computer is reading 350ft.

That's because of normal atmospheric pressure change, just follow directions for re-calibrating (re-set to home altitude) before each ride.

Hi,
I've had barometric pressure altimeters on a number of bike computers for 10 years. If you calibrate them before you ride and the weather is "stable" the elevation readings are reasonably accurate (at least compared to roadside signs). However, I am generally too lazy to calibrate so I generally just used the elevation gained numbers which are close enough with or without calibration.
My Garmin 705 (and later Garmin computers) has a feature where if I'm starting from home (or some other preset location), it resets the elevation to match a preset elevation that I input. Even with that, if the weather is changing, the absolute elevation numbers can be pretty far off.
